What Happens To Your Body When You Stop Eating Carbs?

C

arbohydrates are like the energy source that keeps you going throughout the day. These carbs turn into a type of sugar called glucose that your body’s cells use for energy. There are different kinds of carbs. Some are like fast-burning fuel, while others are like slow-burning fuel. Fast-burning carbs, found in sugary things like candies and soda, give you quick energy, but it doesn’t last long. On the other hand, slow-burning carbs, which are in foods like whole grains, veggies, and beans, give you steady energy that lasts longer.

Lately, lots of people have become interested in diets with fewer carbs or almost no carbs. They believe it can help them lose weight and feel better. This idea has become popular, and many people are on board with how it affects them. But before you dive into the no-carb diet, there are a handful of things to know to help you make adequate choices.

What happens when you switch to a low-carb diet?

• Glycogen depletion and water loss: Your body stores carbs in the form of glycogen in muscles and the liver. When you go on a low-carb diet, your glycogen stores deplete, and with every gram of glycogen, your body also stores water. As this glycogen storage is used up, you’ll experience initial weight loss due to the water loss. This can give the impression of quick progress, but it’s mostly water weight.
• Blood sugar fluctuations: Carbs play a major role in regulating blood sugar levels. Without regular carb intake, your blood sugar can become unstable, leading to fluctuations in energy levels and mood swings. Some people might experience irritability, fatigue, or difficulty concentrating when their blood sugar drops.

• Ketosis and fat adaptation: One significant change that occurs when you stop eating carbs is the shift to a state called ketosis. In this state, your body starts using fat for energy instead of carbs. This metabolic switch leads to the production of molecules called ketones, which are used as an alternative fuel source. This process can take several days to weeks to fully kick in.
• Initial energy drop: Initially, you might feel tired and low on energy. This is because your body is used to utilizing carbs for quick energy, and it takes time to adapt to burning fat efficiently. This transition period is often referred to as the keto flu, during which you might experience fatigue, headaches, and even nausea.
• Potential for weight loss: Many people turn to low-carb diets for weight loss. The reduction in carb intake can lead to a decrease in calorie consumption as protein and fat can be more satiating. Moreover, the shift to fat metabolism could enhance fat burning and lead to weight loss over time.
• Improved insulin sensitivity: Some studies suggest reducing carb intake can improve insulin sensitivity. This means your cells become more responsive to insulin, the hormone that helps regulate blood sugar. Improved insulin sensitivity can be beneficial for managing conditions like type 2 diabetes.
• Changes in food cravings: Without the constant influx of carbs, your cravings for sugary and starchy foods might decrease. This can be advantageous for those struggling with sugar addiction or overeating.
• Impacts on exercise performance: Initially, your exercise performance might suffer due to the lack of easily accessible glucose, which muscles use for quick bursts of energy. However, as the body adapts to using fat for fuel, some endurance athletes find their long-duration performance improves.
• Brain function and mood: Your brain typically relies on glucose for energy, so the switch to ketones can affect cognitive function. Some people report improved mental clarity and focus after adopting a low-carb diet. However, the transition period could also lead to temporary difficulties with concentration and mood swings.
• Nutritional deficiencies: Carbs are a primary source of dietary fiber and certain vitamins and minerals found in plant-based foods. Cutting out carbs without careful planning could lead to deficiencies in nutrients like fiber, B vitamins, and antioxidants.
• Long-term sustainability: While low-carb diets can be effective for weight loss and specific health conditions, some people find them difficult to sustain over the long term. Strictly avoiding carbs can be socially challenging, and could lead to “yo-yo” dieting behavior in which people struggle to maintain their target weight during their weight loss programs.
• Possible health risks: Depending on the types of foods chosen to replace carbs, there might be health risks. For instance, if low-carb diets lead to increased consumption of unhealthy fats, it could negatively impact heart health.
